	WARNING: do not use Pete Kaiser's emacs function "gs-toc" alone to
	re-create the table of contents here, because it will replace the
	hand-edited TOC subheads with a separate subhead for each H2 in
	the body of the file.  Or if you do, first look at the original
	TOC to see how to edit it for visual conciseness.
